My understanding is that the activation issue occurs when the XM receiver is
not used for 90 days and the XM system thus suspends the account.


I'm not sure about this particular "feature," but all of the pilots I've
heard mention this issue claim that it can change from day to day.
Activate it today and receive weather, and tomorrow it shows as
unactivated and needs to be re-activated. This seems to be a problem
that's been mentioned on a number of different forums by users with the
WxWorx receiver. However, some users seem to experience it and others
don't, and some of those who have experienced it chronically have had
their XM receivers replaced and no longer have the problem. I've heard
various theories as to what the problem is, but it sounds like it could
be an XM problem that the newer receivers are working around.
